A novel all solid-state composite polymer elec-trolyte, PEO-LiClO4-LiZSM5, by using 搒hape-selective?molecular sieves ZSM-5 as filler was obtained by the solvent casting method. The experimental results showed that the addition of LiZSM5 could enhance the ionic conductivity of the pristine PEO-LiClO4 electrolyte, the ionic conductivity of PEO10-LiClO4-10%LiZSM5 achieved 1.4×10-5 S cm-1 at 25℃. Lithium ion transference number was tested by AC impedance combined with the steady-state current method, the results showed that LiZSM5 could improve the Li+ transference number of the CPE effectively. The broad elec-trochemical stability window ensured the use of PEO-Li- ClO4-LiZSM5 as electrolyte materials for all solid-state re-chargeable lithium ion batteries.
